HYDROCARBON-BURNER APPARATUS.

Specification of Lette'zs Patent.

Patented May 9, 1922.

To ali whom t may concern:

Be it known that I, C'ARLETON A. ORB, a citizen of the United States,residing at Pueblo, in the county of Pueblo and State o f Colorado, haveinvented certain new and useful Improvements in Hydrocarbon- BurnerApparatus; and l do hereby declare the following-to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to hydrocarbon burners, the improvements beingmore particularly intended for use in connection with a water boiler orsteam generator such as used in steam automobiles, although theimprovement-s can be used in hydrocarbon burnersgenerally for which theyare suited'.

One object of the invention is the provision of novel means for mixingthe air and fuel, and to thoroughly atomize the fuel in so doing,whereby the mixture is' quickly ignited and the combustion thorough.

Another object is the provision of a hydrocarbon burner apparatus usinga fan or blower for furnishing a copioussupply of air under pressure,and novel mea s whereby such blower is operated automatically to supplyair when fuel is delivered, thereby simultaneously establishing thesupply of air and fuel and likewise simultaneously cutting off suchsupply, under the control ofv an automatic pressure valve or the like.

A still further object is the provision of such an apparatus including aspark plug or igniter for igniting the fuel, andA automatic means forbringing such igniter into operation when the flow of fuel 'and air isstarted and for automatically cutting out such ig-A understood thatchanges can be made within the scope of what is claimed without def-parting from the spirit of the invention.

Figure 1 is a diagrammatical view of ther apparatus.

Fig. 2 is a fragmentary detail View showing a modification. f

The apparatus is illustrated as designed for use on a steam motorvehicle, but can be used for other kindred purposes, and, a's

shown, the apparatus includes a steam generator or boiler 1 having theburner pan or bowl 2 at the bottom (which may be lined with asbestos orother refractory material) and the smoke cap 3 at the top from which thechimney 4L extends for the outletof the product of combustion. The fuelis delivered into the burner pan 2 at one 'side through any suitablenozzle 5 from a fuel tank 6, and theapparatus' will burn kerosine,gasoline, alcohol, crude oil and other fuels, successfully. A pipe 7leads from the tank 6 and has a manual controllin,-grv

valve 8 for establishing and stopping the:

How of fuel manually, and said pipe 7 leads" to an automatic pressure'valve 9, from which the fuel supply pipe 10 leads to the;`

the -tank '6 so as to flow under pressure-to and through the nozzle 5,and, for this purpose, the compressed air tank 12 is provided, and maybe' dis osed next to the fuel tank 6. The tanks 6 an 12 have therespective pressure gages 13 and'lll, the air i-n the tank 12.

being under high pressure, whereas the pressure in the tank 6 iscomparatively low. The' tank for convenience in pumping air Vinto saidneck 16 throughwhichlth'e fuel ispouredl ljinto l:the tank. The air isdelivered from 12 has a valve and hose connection' 15. s. 95,- y tank'at intervals, and the tank 6 has aiilling` v tank 6, but restrictingmaintain a predetermined low pressure in the tank 6. The neck 16 has avalve chamber moved for filling the tank 6, the valve 2()` the a set ofvanesl24 within'the delivery'porrtion of the'airv conduit `waste whenthe cap 21 is removed for filling etc. lVith the r the tank 12 into thetank 6 by means lof an airy ipe 17 leading romthe tank 12 and pre.erably `connected to the neck 16. A.

ressurereducing valve 18 is disposed in the piple 17 for the passagesuch iow s0 as Yto 1 9 therein into which the air flows from the pipe17, and a check valve 20 is ldisposed in ligging normallyheld open4 ,bythe Ccap 21 whic the chamber `19,

is removably secured on the neck 16, whereby when said cap is reisreleased so as to ,prevent -the discharge and ofair from the tank 12.vIn this manner fuel tank 6, the flow of air-from the tank'12 isautomatically stopped, 'and such tlow will be reestablishe'd when thecap 21 is again' applied tothe neck 16. 'The valves will deliver the uelthe tank 6 to the deery nozzle 5.

chimneyI 4L' The air conduitV 23 extends from the blower 22 and deliversthe air into the burner pan 2 opposite to the fuel nozzle 5, whereby theinfiowing streams of fuel and air are directed toward Aone another inopposition, both the air and fuel beingunderA pressure. y nozzle 5V andthe air` and fuelirnpinging,r against vone another, will result in theparticles of -fuel being broken y11p-into a fine similar to .theactionof the windqwhen' striking water` delivered from mist or vapor',

a hosenozzle. which causes the drops of water to be broken into a finemist. vln this way, the fuel is thoroughly atomized and mixed with theair, and ,n be lighted instantly without using a carbureter, va porizer,generator or similar appliance. This simplies burner plates, vvaporizer,

present arrangement, the fuel and air are delivered into they burner'chamber from opposite directions and this will vaporize the fuel andmii; thefuel and air thoroughly., It isxpreferable to' provide or pipe23, which are twisted into helical'4 .orL spiral forni wherebyhrto'.givethe` stream of air a whirlf' ingr motionuthereby enhancing. thvaporizatioh'of'the fuel' and mixture of fueland air. The operating`means of 'the blower` 22l embodiesv anlelectrie an electrical circuit ahydraulic' '.or pressure of air into the uelI fthe lpressure is low,

creased. Thus, when lthe blower 22 operated to -into the burner and Anair fan or blower-.22 is used for-sup` ying an abundant flow of air tomain-V ."t'aln combustion and to vcreate a forced `draft through theboiler and" down the y interval.` The fuel is sprayed from the,

`the burner and the Ation in steamV pressure in motor '25, disposedlin26 having 'the battery" 27 or other source of electrical energy, and;switch 28'is'dis-fl more, the closure of the switch 28l enables 139thereto a branch pipe'29-leading from the Jfuel supply pipe 10 at thatside of the valve 9` opposite to the fuel Atank 6, Any suitablehydraulic or pressure switch can be used, whereby to normally open thecircuit when v and to automatically close the circuit .when the pressureis inthe valvesS and 9 areopen, the pressure of the fuel vfrom the tan-k6 will close the switch 28, in order that when the fuel is deliveredfrom the nozzle 5, the motor circuit will be instantlvclose'd andfurnish air at 'the is kdischarged into the whenthe `steam pressame timethat fuel burner. Conversely,

vsure closes the `valve 9, to shut' off the fiow of fuel, the reduction1n' pressure will auto? matically open the vlow 8, so as to stop theblower at the instant that the discharge of fuel is stopped. The fueland air are thus automatically and simultaneously delivered shut ofi'according to pressure.

In order to'ignite the fuel when*` the flow of fueland air is started,4a conductor 3Q 9()v Ais branched from 'the circuit'26 as a shunt f'parallelwith the motor 25, and has connected therein an electricautomatic cut ofi' time switch 31 of any suitable kind, and theconductor 30' leads through the primary coil 95 of an ordi-nary orsuitable spark coil 32, the switch 31 operating to' open the spark coilcircuit after ythe current yiowsfor a short; The switch 31is normallyclosed, so thatvwhen the rent will `flow through both the motor `25 andspark coil 32, but the switch 31 will coil circuit after a short in-nterval whereas, vthe motor 25 lcontinues to operate. The secondarycircuit 330i the 105k spark coil 32 is connected to the spark plu origniterll, and the spark coil' 32,. wi

as usu'ahifmiucey a highpotential current 1n willA result in 'theigniterfi igniting the.' l fuel, it being noted :that the igniter isenergized at the instant the .fuel is delivered into fiow of au started.In operation, supposing that the valve 8 `115 is Vclosed so that Vtheapparatus-is at rest,

To start the burner,.thezvalve 8 is opened,` and Ythe fuel willlowpastsaid valve 8 .and/'51 valve 9 through pipe 10 and nozzle 5;'.

and at the same time, the switch `26 is closedjl Lby the fuel pressure,thereby closing the' motor circuit and starting theI blower 22. Theairis 4thus supplied at the same time thatthe How of fuel is started, and,furtherswitch 28 is closed, the cur-v 100 or circuit 30, which' 110 offuel for thoroughly 'fuel and the switch 28 will stop the blower.

. combustion chamber,

release the electric current to flow past the switch 3l therebyenergizing the spark coil 32 which will result in the igniter 34igniting the fuel immediately upon entering the burner chamber. Theigniter 34 is stopped after a short interval, by the automatic openingof the switch 3l, and the ignition device is thus brought to rest, as itis no longer needed after the fuel is lighted, being only Abrought intooperation when the flow of fuel and air is first established afterhaving been cut down.- When the steam pressure increases 'to a point forwhich the valve i9 has been adjusted, said valve will be closed, therebyshutting olf the flow of then open to When 'the pressure of steamreduces; the valve 9'will open, there by recstablishing' theflow offuel, closing the switch 28 to start the blower and, at the same time,energizing the igniter 34E, the same as before.

In the modification shown in Fig. 2, the

fuel nozzle 5 is locate-d centrally of the vanes 2l within the airconduit 23, whereby the air and fuel enter the burner chamber from thesaine direction, and such venes will whirl the air around thedischarging stream atomizing and mixf ing the fuel. This arrangement,however, will Anot have the advantage of the opposing streams of air andfuel striking one another as in the preferred form.
